APPARATUS FOR PRODUCING REFRIGERATION.

Application nica october 14. 1911.

To all 'whom it may concern Be it known that I, Micronet J. Riounilx, a citizen of the United States otn America, residing at Bisbee, in the county ot'v Cochise and State of Arizona, have invented certain new and useful improvements in Apparatus for .Producing Ret'rigeration7 oli' which the following is a specilication.

The 'present invention relates to a process o and apparatus 'tor refrigeration andhas for its purpose to` devise a method of eX tracting heat from the space which is to be refrigerated; and to accomplish the same in a more expeditious, coi'ivenicnt, and cheaper manner than heretofore proposed.

The further purpose :is to devise a process of refrigeration which may be carried out in practice whether the space to be cooled be an ice chest, ordinary refrigerator, or room and in tact may be utilized for cooling comparatively large spaces such buildings.

With these and other objects in view the invention consists in the arrangement and combination of parts hereinafter claimed, and while the invention is notrestrictcd to the enact details shown and described, still for the purpose, of disclosure reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views.l and in which :m a suitable apparatus for Imrryingl the prin ciples into effect is shown in the accompanyingr drawings whereinz- Figure l is a front elevation o'l an ordinary refrigerator with my improved appara tus installed. Fig. 2 is a central vert-ical sectional view thereof. Fig. 3 is a vertical sec` tional view taken at lright angles to Fig. f3. Fig. le is Va transverse sectional view of Fi Z taken on the line 4.--4; and Fig. is adel tail view in front elevation 'disclosing one oi the water evaporating devices.

Referring' to the construction in detail and wherein like characters ot' reference indi cate corresponding parts in the ditlerent views shown l designates the refrigerator outer walls and Q the inner walls thereof i1which are spaced from said outer walls l. to

receive suitable packing 3 oi non-heat conducting material. The bottom-Ll ol the re` frigerator is in .like manner spaced Alrom the bottom 5 of the inner walls and the snlce beis also filled with packing' 6.

Mounted within the chamber provided by i Specification of Letters Patent.

Patented Nov. 24, 1914.-. serial No. 654,766.

.the inner walls 2 is a metallic casing consisting of an upper section 7, a lower section 8. and an intermediate sectionl),` said sections being suitably connected as by the corner angle bars ll). Said sections are of such dimensions .as will provide a iront space o1' chamber l1 and a similar and rear chamber lolzh of the chambers llV and l2 extend .tor substantially the iull height of the frigor-atei', and the bars 10 provide transverse chambers or passage ways 13 and 1-l which allord direct communication between said chambers 11 and 12 for the purpose which will be presently set forth'.

The upper section 7 contains a casing or receptacle l5 which is suitably spaced .from the walls of said section to receive a packing 10, the purpose of which will be obvious. The receptacle 15 has mounted therein a plurality, prch-:rably three,'trays or pans 17, 1S and 19 adapted to contain the water or other liquid which is to be evaporated. yTwo se` ries of pipes Q0 are disposed in parallel re! lation and immediately over 'the trays 18 and 119 and are secured in position through the medium of the inner and outer walls of the upper section 7, as shown in F ig. 2.; In like manner a. series of parallelpipes 2l is located over the upper tray 17, and said pipes 2l are similarly secured within the casing 7. The series of pipes 2O bring the front and rear chambers ll and l2 respec tively into direct communication while the series of pipes 2l arc provided with upwardly extendingy portions 2Q that communicate with the atmosphere, and at their rear ends said pipes ill communicate with the passage way or flue 23 as clearly shown in Fig. The line 23 extends vto a point below the intermediate section 9, and communicates with the lower section 8, and into which it delivers currents of cool air which was taken in at the inlets 2Q as will be pres-` ently explained.

rThe lower section 8 is provided with trays or shelves on which may be supported the toed-stuffs to be preserved, and access is had to said shelves through a door 25 having hinges E26 that are secured to the refrigerator outer wall. A. pipe 2T serves to communicate the lower section S with the atmosphere to carry ofi' the air brought in by the pipe 23.

The intermediate section 9 is provided with a corrugated bottom or tray 28, that is designed to support a block of ice in the event that ice is to be used. A drip pipe 29 extends from the chamber of the receptacle 9 to a point below' the refrigerator as shown in Fig. 2. A water cooler 30 is secured within the chamber of the section 9 and has a faucet 31. Access is had to the chamber of the section 9 through the medium of the door ,32 that is mounted on hinges 33 secured to the refrigerator outer wall.

Iihe spaces 11 and 1,2 are designed to receive brine which constitutes the refrigerant and said refrigerant has its temperature constantly kep'J to a low degree through the principle of water evaporation to which end the several water trays in the upper section are provided. Eraporation of the water in these trays is effected through the medium of fabric sectie-.is 34 thatI are hung over thc pipes Q0 and 21 in close arrangement. Each of said pipes is further provided withthe brous covering 3.5. The fabric sections 3i are secured t wire fabrics 36; which overlie the fabric.,i Bain preferably that manner shown in Fig. The 'ends of the fabrics 34.

are so adjusted as to be submerged in the,

water or other liquid contained in the trays; and through capillary attraction 4the water in these trays'is being constantly absorbed by the fabrics 311 and from said fabrics the water is evaporated as will be understood. .To facilitate this evaporation the refrigeraltor outer walls 1 are cut away as at 37 in.

Fig. 1 which; as will be understood, exposes all of theI series of fabrics to the external atmosphere..

In operation the brine through haying its temperature lowered by the cooling pipes 20,

due to the water evaporation as just eX` plained, tends to iiow downwardly or around that portion of the refrigerator which is designed to be cooled and as the temperature rises said\ brine will tend to travel upwardly whence it can pass thrbugh a series of pipes 20 and has its temperature again lowered. In like manner the currents o air-passing through the pipes 21 is caused to pass downwardly through the passageway Q3 and into the chamber of the lower section 8 from which chamber said air passes oli through the pipe 27 as its temperature rises.

` What I claim as new and desire to protect by United States Letters Patent is 1. In a refrigerating apparatus, the combination of vessels adapted to hold brine;

pans between said vessels adapted to hold g water for evaporation; a Closed-conduit conover; and means for spreading water from said pans over said conduit and said pipes.

2.
